There are currently three public projects.
- dl.google.com
- vitess
- Google App Engine, that used to be maintained by someone on the Go team not the Google App Engine team, if the Google IO information is still valid.
Chrome is focusing on Dart support and Android team was very explicit at Google IO about Java being what really matters.
So any other very successful Go projects at Google that can be shared?
EDIT: For those that bothered to provide answers. Thanks.
